Question

(c) The structure shown in Fig Qlc is a plane pin-jointed structure made from identical Aluminium tubes 2m in length having an axial stiffness of 8MN/m and subject to a point load as shown. Fig Qlc 2 m Show on a sketch how the structure can be modelled exploiting the vertical axis of symmetry. For the symmetry model, indicate all restraints and loads, set up a system stiffiness matrix and indicate the active and inactive degrees of freedom. There is no need to solve the system for this problem. (40 marks)
